SPRAYING APPARATUS.

Application filed July 8, 1826 Serial No. 120,278.

This invention relates to spraying apparatus and has for an object to provide an apparatus by means of which a coating or protective film of liquid preservative ma be applied to the exposed surfaces of rai way road beds, ties, switches, fastemngs and the like.

The invention relates to an apparatus which may be propelled over a track and which While in motion or at rest will apply to the road bed, ties, fasteners, etc, a protective coating of a liquid adapted to prevent corrosion of exposed metal surfaces and weathering of Wooden surfaces, while at the same time laying dust and destro ing vegetable life which would ordinarily ave to be destroyed by more cumbersome methods, the particular feature to which the present invention is confined being the transversely extending spray pipe of said apparatus. The herein described apparatus is adapted for spraying any desired liquid such as metal preservatives and weed killers. It has, however, been found that certain petroleum products are particularly well suited for use as metal and wood preservatives and destroyers of plant life, and the apparatus of this invention Will be described for the purpose of illustration as adaptedfor the spraying of oil.

In order that the invention may be thoroughly understood, I will now proceed to describe and illustrate a referred embodiment of the same in the ollo'wing specification and will then point out the novel features in appended claims.

. In the drawings; t

Figure 1 is an end elevation of the spraying apparatus of this invention together with the nozzles for spraying the rai s and the ends of theties attached to the end of an ordinary flat car.

Figures 2, 3, 4, 5, 6, 7, and 8, are de tailed views on an enlarged scale of the oil spraying nozzles and associated parts.

The apparatus of this invention and the associated spray nozzles may be applied to an ordinary flat or cabin car without any material modification of the construction of the car, and in the drawings 10 indicates such a car, which is provided with V the usual steam and air connections for attachment to a locomotive. The devices for 5 applying the oil to the ties and road bed are supported at one end of the car as best of which connects with one of the oil disshown in Figure 1. The usual arrangement wh1le spraying a roadbed is to couple the oil spraying car ahead of the required number of tank' cars and they are in turn coupled to a locomotiveiwhich is adapted to push the train at an desired speed. Power for spraying-the oi may be secured either from suitab e pumps located on the 011 car and driven by steam from the locomotive or from a gasoline power station located on the car. The method of obtam-ing power is optional and any suitable means may be used for the urpose. The spraying apparatus is attache to one end of the oil car and is suspended above the rails and roadbed by suitable brackets or supports such as 11 and 12 attached to the underside of the car.

The spraying fluid, which in this illustrative example is oil, is pumped from the tank cars through a main supply pipe 13 which is connected with branch pipes 14, 15, and 16. Pipe 14 leads to and connects with a horizontally disposed perforated i e 17 at a point intermediate its so ends. e p1 pe 17 which embodies the present mvent1on is closed at its ends and is of a length sufiicient to extend across the tracks an located as nearly as possible to the top of the rails 18.

Pipe 17 is formed with a central bore 19 (see Figure 8) and with two parallel rows of holes 20 extending through the wall of the pipe and communicating with the central bore. The holes in the two rows are oppositely inclined and are directed downwardly m such a manner as to spray the top and the front and rear faces of the ties as well as that portion of the roadbed between the ties, as the oil car proceeds along the track.

In order that the oil may be discharged from the holes under sufiicient pressure to insure that the jets of oil will-reach the top and faces of the ties before being broken up by the rush of air resulting from the movement of the oil car, the. pipe 17 is formed with longitudinal air conduits 21 with a plurality of branch conduits 22 each and to prevent the building up of any back pressure in the oil line due to the movement of the car. Air under pressure is supplied of the ties, as well as the to s, are sprayed tion of the road with an even up lication 0 oil. The secd immediatel adjacent to the sides of the ties receives t e .smallest application of oil'while the tops of the ties receive a double application (see Figure 8).

So that the ends of the ties and that part of the road bed immediately adjacent thereto may be s rayed, there may be rovided spraying evices in the form of a justable spray nozzles 26, 26, at opposite sides of the apparatus. These nozzles which are not 4 herein claimed are positioned outwardly of the ends of the ties and are directed downwardl and inwardly so that the atomized oil discharged therefrom will completely cover the exposed portion of the ends of the ties as the car advances. Oil is supplied to each of the nozzles 26 from the main supply pipe 13, the oil passing through branch pipe 16 and a valved extension pipe 27 communicating therewith and extending in opposite directions to connect with the two nozzles. The nozzles each have an oil conduit 28 communicating with the pipe 27 through a port 29. The nozzles are each formed in two arts-a stationar member 30 and a mova le member 31. e member 31 may be so rotated with respect to the stationary member 30 that the conduit 28 may be brought into and out of re 'stry with the port 29 to either permit or s ut off the flow of oil, as may be desired. I

The movable member 31 is also provided with an air conduit 32 adapted at certain times to register with a port 33 through which air may be admitted from a valved pipe 34 which connects through pipes 24 and 25, with a source of air under pressure (not shown). Pipe 25 is provided with a valve 37 operated from the floor of the car 10 by means of a lever 38.

Auxiliar air pipes 39 having check valves 40 a so connect pipes 24 with thefnozzles 26 and may be used for cleaning out the orifices.

The movable portion of the nozzles 26 is rotated to control the supply of oil and air by means of a series of pivotally connected levers 35, 36, 41, and 42 o ated by means of pedals or levers 43 on t e car 10. When passin obstructions such as hand switches or the like, the nozzles can be readily raised so as to pass such obstructions without danger of striking them or they can be adjusted so as to spray the ends of average, short, or lon length ties, as occasion requires.

Ad itional pairs of nozzles indicated generally at '44, 44, which may be termed rail nozzles in order to distinguish them from the tie nozzles 26, 26, may be provided for the purpose of spraying the sides of the rails, each pair being adapted to spray the opposite sides of a single rail. The two pairs are of identical construction and only one will be described in detail.

Each nozzle consists of a movable substantially V-shaped element 44, one arm 45 of which is formed with an air conduit 46 and with an oil conduit-47 both of which discharge into the other arm 48 of the nozzle from which the oil is ejected b the air against the side of the rail 18. he ends of the conduits 46 and 47 are' adapted, when the nozzle is depending so as to direct its spray against the side of the rail 18, to register with similar air and oil conduits 50 and 51, respectively, in a casing 52, which conduits are in turn connected to the air and oil supply pipes 36 and 13 respectively, by pipes 53 and 54. The nozzles are normal y held in operative position by means of coil springs 55 but can be raised or low ered at will by means of a lever 56 which extends to the car floor and may be operated therefrom. It will be seen that as soon as the nozzles are raised communication between conduits 46 and 47, and 50 and 51, respectively, is cut oil, thus stopping the free flow of air and oil to the nozzles.

From the foregoing, it will be seen that the herein described apparatus is adapted for s raying not only the sides of railway rails ut is equally well adapted for spray ing the ties, road bed, fasteners and fittin s. The construction of the apparatus and t e arrangement of valves is such that the separate spraying elements can be operated simultaneously or may be selectively operated as desired.

An apparatus of preferred form and construction has been illustrated and described for the purpose of showing a we in which this invention may be practiced, ut the in ventive thought upon which this application is based is broader than this illustrative embodiment thereof. It. is, therefore, understood that the scope of the invention is not limited by the present'disclosure, reference being had to the appended claims for that pur ose.

What claim is:

1. The combination with a car adapted to be propelled over a railroad track, of a horizontally disposed tubular member extending transversely across the track and havin a central bore constituting an oil conduit and formed with a plurality of rows of outwardly inclined outlet ports communicating with the bore thereof, air conduits extending longitudinally through the wall of the tubular member, branch air conduits connecting each of the outlet ports with one of the air conduits, the connection between the several branch conduits and the outlet ports being at a suflicient angle to wardly inclined outlet ports communicating 10 with the bore thereof, a main air conduit extending longitudinally through the wall of the tubular member, branch air conduits connecting each of the outlet ports with the main air conduit, the connection between the several branch conduits and the outlet ports being at a suflicient angle to provide for the positive discharge of oil therefrom,

and means for supplying oil and air to the .oil and air conduits, respectively.

In witness whereof I have hereunto set 20 my hand this 26 day of June, 1926.
